## Session Summary

Multi-stream session. Two GuruRMM server bugs were diagnosed, fixed, and deployed to production,
and a substantial new fleet capability — the `unifi-wifi` tuning skill — was researched and built
against the self-hosted UOS controller.

**GuruRMM BSOD duplicate alerts (fixed + deployed).** Triaged a dashboard showing two identical
`VIDEO_TDR_FAILURE (0x116) on MSI` CRITICAL alerts. Root cause: the BSOD alert `dedup_key` was
`bsod:<agent>:<dump_sha256>` — unique per crash, so every recurrence spawned a new alert. Worse,
because `alert_mutes` keys on `dedup_key`, the "ignore permanently" Mike had set only matched the one
dump it was placed on, so each new crash re-alerted (a perma-ignore failure, not just a cosmetic
duplicate). Changed the key to `bsod:<agent>:<bugcheck_code>` (stable across recurrences). Committed
`f0a4b7f`, pushed → the build pipeline deployed server v0.3.73. Then corrected the live state on
`.30` via psql: retired the stale per-dump mute, inserted the correct stable-key mute for MSI
(`bsod:a685af29-...:0x116`), and resolved the 2 active duplicate alerts. Verified: MSI BSOD alerts
now 0 active.

**GuruRMM MSI cache EXDEV (fixed + deployed).** Explained a `gururmm_server::api::install: Failed to
move MSI to cache` server_error. The site-MSI builder staged the signed MSI in `std::env::temp_dir()`
(`/tmp`, a tmpfs on `.30`) then `rename`d it to `/opt/gururmm/downloads` (root LV) — a cross-device
rename that fails with EXDEV, so every site-specific MSI build 500'd. The signed-EXE path already
staged in `downloads_dir` for this reason; the MSI path was the outlier. Fixed (stage temp in
`downloads_dir`), committed `95ef901`, deployed server v0.3.74.

**UOS dedicated SSH key (Howard unblocked).** Howard was blocked on UOS controller (.29) access for
Cascades RF work. Generated a dedicated ed25519 keypair, installed its pubkey on `.29` root, and
vaulted it (`infrastructure/uos-server-ssh-key`, base64 in `ssh-private-key-b64`). Wired
`uos-mongo.sh` to auto-resolve it so any fleet machine works. Replied via coord.

**`unifi-wifi` skill (the main build).** Researched what the UOS controller exposes for RF tuning,
corrected an early wrong conclusion (the history is NOT in the `ace` config DB — it's in **`ace_stat`**:
`stat_hourly` per-AP/band `cu_total`/`cu_interf`/`num_sta`, and `wifi_connectivity_event` = the roam
graph). Built: `audit-site.sh` (config + foreign-interference audit), `model-rank.sh` (airtime-reduction
ranking), `optimize-radios.sh` (coverage-safe power-down/disable planner, multi-model-hardened via
Grok+Gemini), `live-stats.sh` (controller live API, needs a vaulted admin), `watch-ap.sh` (per-AP
real-time RF watch via direct AP SSH). Confirmed direct AP SSH is feasible (device-auth vaulted
`clients/cascades-tucson/unifi-ap-ssh`); needs the Cascades VPN for L3 reach. Messaged Howard the
handoff.

## Key Decisions

- **BSOD/mute key on `(agent,bugcheck)` not dump hash.** One fix resolves both the duplicate alerts
  and the broken perma-ignore (both ride on `dedup_key`). Counting is preserved (every dump still in
  `bsod_events`); muting only suppresses the active alert + email.
- **Deploy via push (webhook pipeline), DB cleanup via psql on `.30`.** The pipeline auto-builds on
  push to `guru-rmm` main; the existing duplicate alerts and the corrected mute don't self-fix, so
  applied them directly in Postgres.
- **UOS key: dedicated keypair, not the standard key.** Vaulting GURU-5070's broad personal key
  fleet-wide was rejected; a dedicated, revocable key scoped to `.29` was generated instead.
- **Vault multiline keys as base64.** `vault-helper --set` collapses multiline values to one line
  (corrupts SSH keys); store as `*-b64` and decode on use. (Root cause of a failed key round-trip.)
- **WiFi coverage model = the roam graph, not distance.** Materials-aware by construction: Cascades'
  steel-reinforced hallway walls block cross-hall RF, so clients never roam across them and the model
  never calls those APs redundant. Distance/floorplan is only a prior; RF/roam evidence is the truth.
- **Power-down now, disable later.** Cascades airtime data robustly supports powering down ~all 2.4
  radios (safe, keeps BSSID); roam data is too sparse to PROVE coverage redundancy for disables, so the
  optimizer recommends 0 disables until the live AP-to-AP RF neighbor table (API wireup) exists.
- **Multi-AI on design AND implementation.** Grok+Gemini critiqued the optimizer design (caught the
  capacity-cascade risk → added load-shift simulation; bidirectional roams; band-specific RSSI;
  40%/zone cap; retries normalization).

## Problems Encountered

- **Vaulted SSH key didn't round-trip** (`libcrypto: unsupported`): `vault-helper --set` mangled the
  multiline key to one line. Fixed by storing base64 (`ssh-private-key-b64`) + decode on use.
- **`tx_retries` shown as 958%/6317%** in the optimizer: it's a raw count, not a %. Normalized by
  `wifi_tx_attempts`.
- **Optimizer over-classified "isolated-essential"**: sparse roam data → almost no strong neighbor →
  everything looked isolated. Resolved by making POWER-DOWN (coverage-safe) the default for saturated
  radios regardless of neighbor evidence, reserving DISABLE for radios with positive coverage evidence.
- **`6e` as a JS object key = SyntaxError** ("missing exponent") in mongo-shell JS (parsed as a number).
  Quote it (`'6e'`) or avoid it as a bare key.
- **RMM SYSTEM context vs user mapped drives** (earlier in session, logged as correction): an AP/UNC
  redirect check under SYSTEM read False; the share existed in the user session. Diagnose in `user_session`.

(dedicated key), `wiki/systems/jupiter.md`, `wiki/clients/internal-infrastructure.md`.

guru-rmm (submodule, deployed): `server/src/ws/mod.rs` (BSOD dedup_key, `f0a4b7f`/v0.3.73);

DB (gururmm Postgres on `.30`): alert_mutes for MSI corrected; 2 BSOD alerts resolved.
Memory: `feedback_rmm_system_context_mapped_drives.md` (+ MEMORY.md line). errorlog: RMM-SYSTEM correction.

## Credentials & Secrets

- **UOS dedicated root SSH key** — vault `infrastructure/uos-server-ssh-key` (private key base64 in
  `credentials.ssh-private-key-b64`; pubkey in `/root/.ssh/authorized_keys` on `.29`). Decode:
  `vault.sh get-field ... credentials.ssh-private-key-b64 | base64 -d`.
- **Cascades UniFi AP device-auth SSH** — vault `clients/cascades-tucson/unifi-ap-ssh`: user
  `gUJiB84lr6C4`, password `RJE3VIqXiA8Gj` (all Cascades APs; needs Cascades VPN to reach 192.168.2.x/3.x).
- **UOS cloud Site Manager API key** (from earlier) — vault `infrastructure/unifi-site-manager-api`
  (`amY54KqX0i0OuGEYNykLdH9M1Kd4jhzt`); works on api.ui.com for adopted devices only, 401s the local API.
- **gururmm Postgres** (used for the alert DB fix) — vault `infrastructure/gururmm-server-physical`
  `credentials.databases.postgresql-*` (db gururmm / user gururmm).

## Infrastructure & Servers

- **GuruRMM server `.30`** (hostname gururmm, Ubuntu): systemd `gururmm-server`; repo `/home/guru/gururmm`;
  binary `/opt/gururmm/gururmm-server`; build log `/var/log/gururmm-build.log`; push-to-main webhook
  auto-builds+deploys. SSH `infrastructure/gururmm-server-physical`. Now at v0.3.74.
- **UOS Server `.29`** (unifi.azcomputerguru.com → `:11443` via NPM; Rocky 9; UniFi Network = ace.jar +
  Mongo `ace`/`ace_stat`/`ace_audit` on 127.0.0.1:27117 inside rootless podman `uosserver`). Cascades
  site `_id 685f39068e65331c46ef6dd2`, short `va6iba3v`, 77 APs (U7-Pro/6E) + 12 switches.
- **MSI BSOD agent** `a685af29-ef35-46da-ac3d-431e713b70ab` (recurring 0x116; being replaced).

## Commands & Outputs

- WiFi audit/rank/optimize: `bash .claude/skills/unifi-wifi/scripts/{audit-site,model-rank,optimize-radios}.sh cascades`.
- UOS Mongo (incl. ace_stat): `bash .claude/scripts/uos-mongo.sh` (pipe JS; `db.getSiblingDB('ace_stat')`).
- Cascades 2.4 finding: 75 APs, cu_total 74–94%, cu_interf 61–81%, ~1 client each → power-down 74/75, 0 disables yet.
- MSI EXDEV: `err=Invalid cross-device link (os error 18)`; `/tmp`=tmpfs, `/opt/gururmm/downloads`=root LV.

## Pending / Incomplete Tasks

- **Enable the Cascades site VPN** → unlocks `watch-ap.sh` (per-AP real-time) — APs on 192.168.2.x/3.x.
- **Create a read-only UOS Network admin**, vault `infrastructure/uos-server-network-api` →
  `live-stats.sh` (controller-wide live RF + the AP-to-AP RF neighbor table that enables confident disables).
- Howard placing APs on the UniFi floorplan → adds distance-prior edges to the model.
- `optimize-radios.sh` v-next: greedy disable becomes meaningful once the RF table exists.
- (Carried, earlier in day) SP-SharonW11 M365 license removal — coord todo `79d291db`, EOW 2026-06-19.

## Update: 20:48 PT — apply-radio write path, live API RW admin, Howard handoff

Continued the unifi-wifi build into the change-application layer and wired the live Network API
(Plane 2), then handed the skill to Howard.

**Optimizer hardened (multi-AI) + v2 built.** Ran the greedy coverage-safe optimizer design through
Grok + Gemini (both converged): added bidirectional roam requirement, band-specific p25 RSSI bars,
**load-shift simulation** (don't disable into a saturated neighbor = "capacity cascade"), `cu_interf`
as the removable benefit with `cu_self` as transfer cost, normalized `tx_retries` by attempts,
40%/zone disable cap, stepwise output. Built `scripts/optimize-radios.sh`. On Cascades 2.4 it
correctly recommends **power-down on 74/75 radios** and **0 disables** — the roam data is too sparse
to prove coverage redundancy, so disables wait on the live RF-neighbor table. Mike added the
materials insight (Cascades steel-reinforced hallway walls block cross-hall RF) — captured that the
roam graph is materials-aware by construction (cross-wall APs never roam-share, so never look
redundant); distance is only a prior.

**apply-radio.sh (config writes, no per-AP UI clicking).** Dry-run by default (per-AP before->after +
rollback values + REST payload); `--apply` logs into the controller and PUTs the radio change per AP
across a zone, saving a rollback JSON. Power-down implemented; disable deferred (needs the RF table).

**Live API access — the credential saga.** apply-radio.sh/live-stats.sh need a controller admin
session (the SSH key is OS-root, NOT an API session). Tried to auto-provision a Network admin via
Mongo (`ace.admin` + 49 privilege rows) — it can't log in (UniFi OS auth lives in `unifi-core`, not
`ace.admin`; 401/403). Cleaned up the orphan completely. Confirmed the existing SSO admins
(azcomputerguru) are MFA-gated (`499 MFA_AUTH_REQUIRED`) = unusable for the API. Resolution: Mike
created a **local** UniFi admin `claudetools` ("Restrict to Local Access Only", Full Management) and
provided it; vaulted as `infrastructure/uos-server-network-api-rw`. Verified: it's a **Super Admin**
(`network.management: admin`), reads work (live per-AP RF for 77 APs), writes authorized.

**Handoff.** Told Howard the skill is under his control (coord `d106d2a8`); Mike assists on request.
Synced Howard's live-stats.sh accuracy fixes (all-77-APs, device-level satisfaction, `tx_retries_pct`
rate — his key catch: on the rate 2.4GHz @ 11.2% is the real pain band, DFS @ 8.4% is a resilience
risk, not a throughput killer).

### Key decisions (update)
- **Did NOT write config to the live facility** — confirmed `claudetools` write capability via the
  read-only role endpoint (Super Admin), not a test PUT. Real writes are Howard's per-zone rollout.
- **Vaulted the RW admin as base64-safe plaintext under credentials** (single admin covers read+write;
  live-stats.sh falls back to it).
- **Stopped guessing the login after 2 failed attempts** (UniFi OS locks accounts) — waited for the
  exact credential rather than risk a lockout.

### Problems (update)
- **CSRF 403 on writes**: apply-radio.sh used `dict(resp.headers)` (case-sensitive) so the X-CSRF-Token
  lookup missed. Fixed to `resp.headers` (case-insensitive `.get`). The `--apply` readiness check I ran
  hit 3 Floor-6 APs and 403'd (no change made) — should not have run `--apply` on the live site.
- **live-stats.sh site resolution**: treated the 8-char name "cascades" as a short name. Fixed to
  always resolve via `self/sites` (match _id / name / desc).
- **`6e` as a bare JS object key** = "missing exponent" SyntaxError in mongo-shell JS; quote it.
- **vault-helper `--set` can't store multiline** — already handled (base64); reconfirmed.

### Config changes (update)
Created: `scripts/optimize-radios.sh`, `scripts/apply-radio.sh`. Modified: `scripts/live-stats.sh`
(login sys.argv + cred fallback + site resolution; later merged with Howard's output fixes), `SKILL.md`
(apply-radio + live + watch + model sections), `references/interference-model.md` (materials + ace_stat
correction + multi-AI hardening), `references/data-access.md` (3-DB planes). Vault (pushed):
`infrastructure/uos-server-network-api-rw`.

### Credentials (update)
- **UOS Network API RW admin** — `infrastructure/uos-server-network-api-rw`: username `claudetools`,
  password `hmt8dcf9pvz*nuw.YHE` (local, no MFA, Super Admin on .29). Powers apply-radio.sh + live-stats.sh.
- 1Password Agentic-RW service account token: `infrastructure/1password-service-account` field
  `credentials.credential` (ops_...); SA sees vaults Clients/Infrastructure/Internal Sites/Managed
  Websites/MSP Tools/Projects/Sorting (NOT personal). `op` needs `--vault <id>`.

### Pending (update)
- **AP-to-AP RF-neighbor table** (Howard's TODO in live-stats.sh): build from `rogue` BSSIDs x our
  `vap_table` → unlocks confident radio *disables*. Until then: power-down/channel/width only.
- Howard: VPN + watch-ap.sh U7-Pro parser calibration; then per-zone 2.4 power-down rollout.
- Skill ownership = Howard.
